AUTOMATIC VARIABLE-SPEED ADVERTISING CONTRIV'ANCE.

Original application filed my 16, 1921, Serial No. 488,229. Divided andthis application filed July 7, 1923. Serial No. 650,196.

To all whom it may concern:

Be it known that I, FERNAND OUTREY, citizen of the Republic of France,residing at Paris, France, have invented certain new and useful Irnrovements in Automatic Variable-Speed dvertising Contrivances, of whichthe following is a specification.

My invention relates to automatic optical projecting apparatus such asdescribed in my application, Ser. No. 485,229, filed July 16, 1921, ofwhich this is a division.

The object of the present invention is to demonstrate, to impartinstruction, and to advertise, by automatically effecting lumi nousprojection with the minimum of apparatus and without danger.

Now imparting instruction requires the projection to be carried out atany speed suitable for demonstration, from a stoppage of several minutesduration to the qulckest speed possible.

Likewise with advertising, it is frequently necessary to reproduce amovement in a very slow manner, in order that the demonstration can beproperly followed.

One picture needs to be in view for a very short period, another,accompanied by long sente fee or involving comp icated designs, re uiiesto remain longer visible.

he contrivance which forms the subject of the present invention has forits object to carry out the above described variable speed effects inprojection with the assist ance of an operator and sim ly by insertionof'the film or slides, which t emselves carry the means for controllingtheir speed of passage.

A contrivance according to the inventionis illustrated by way of exam leon the accompanying drawing, in whic Fig. 1 is a plan of an assemblageof devices for regulating the speed of the film;

Fig. 2 is a perspective view of the movable contact controllingmechanism of the preceding assemble e; M

Fig. 3 is a plan 0 a separate slide formed with a notch like thepictures of the film of The picture 34 of the film 1 (Figs. 1 andprojector. A contact member 32 is permanently connected by one of itsends in the circuit of an electromotor 8 and engages with its other endin the notch 3031. When the end of the contact member 32 is engaged inthe notch 3031 the circuit of the electromotor 8 is opened, and on thecontrary closes when the member 30 lifts on leaving the notch 30-31 andcomes into engagement with an electric contact 33. The contact member 32has imparted thereto a rectilinear movement of displacement parallel tothe border of the stationary film. The member 32 isfast with the contact33 as regards its movements of translation arallel to the border of thefilm, such that t ese two members 32 and 33 are constantlyIopposite oneanother ready to come into mutual contact.

Various known mechanism can be employed for impartin to the assemble e32, 33 the movements 0 translation era 61 to the border of the film; forexamplg (Fig. 2) the movable assemblage 32, 33 may be secured to one endof a lever 40 pivoted about an axis 46; this lever is on the one handconnected to a pneumatic dash pot-43 and on the other hand to the core41of a solenod 42. The two leads of the solenoid 42 are connected to theterminals 51 52 of a rotary commutator which enables current to be sentat regular intervals through the solenoid 42. A returning sprin 44 iscompressed by the lever 40 and ten 5 constantly to turn same in thedirection of the arrow 45.

The above described device operates in the following manner :--In aninitial position the picture 34 provided with the notch 30, 31 has beenbrought by the electromotor opposite the projector; the contact member32 is engaged in the notch at 30; the contact between 32 and 33' istherefore interrupted and the circuit of the electromotor 8 is broken;the electromotor is consequently stopped and the picture 34 is renderedstationary in front of the projector.

The commutator 50 has at this instant interrupted the circuit of thesolenoid 42, as indicated in Fig. 2, and the solenoid, which is no loner ener ed, ceases to attract the core l and e lever 40. The

com ressed spring 44 consequently actuates the ever 40 and turns same-1nthe direction of arrow 45 about the axis46.

The lever 40 entrains with it the assemblage ofthe two movable contactmembers 32, 33 in the direction of the arrow 35 in a movementapproximately parallel to the border of the film, until the contactmember arrives at the end 31 of the notch 30, 31; this member thenslides along the inclined border of this notch and is lifted until itbears against the lateral surface of the film. At this instant theelectric contacts 32 and 33 come into engagement; the circuit of theelectromotor 8 is closed; the electromotor recommences to rotate andsubstitutes for the picture 34 in front of .1351; projector thesucceeding picture of the At the same time the rotary commutator hasclosed the circuit of the solenoid 42; the solenoid 42, energized,attracts the core 41 and the lever 40 causing them to'turn in thedirection reverse to 45 about the axis 46. The lever 40 compresses thespring 44 and restores the assemblage of the two movable contact members32, 33 to the position shown in Fig. 2, in which position the member 32is engaged in the end 30 of the notch 30, 31 of the new picturesubstituted for the initial picture 34.

The dashpot 43 renders uniform the oscillations of the lever 40 aboutthe axis 46.

The commutator 50 then breaks the circuit of the solenoid 42; theseveral elements of the device are therefore precisely in their initialpositions, except that the picture 34 has been replaced by thesucceeding picture of the film, and the same series of movements arereproduced.

It follows from the above description that the duration of arrest of apicture of the film in front of the projector is a function of thelength of the notch 30-31.

The movement of the member 32 could be in the opposite direction, inwhich case it would be suflicient to rovide a single nick at the point31 or a ole if the member is displaced along the face of the film. The

contact or the release would be effected when ill? movable member sinksinto the nick or The. above description has been made assuming theinventlon applied to a film. The same invention is ap licable toindependent slides cappble of being independentprojected or ing placedin series on a 0 am, disc, band, etc.

Thus Fig. 3 shows a se arate slide formed with an elongated note 30, 31like the various pictures of the film 1 of Figs. 1 and 2.

Claims:

1. In a luminous projection apparatus, pictures movable in front of theprojector, elongated notches formed in said pictures, a movable controlmember engaging in said notches and controlling the mechanism for dislacing said pictures, means imposing on sai control member rectilinearreci meeting movements a proximately para el to the borders of saipictures.

2. In a luminous projection apparatus, pictures movable in front of theprojector, elongated notches formed in the borders of said pictures, acontact lever engaging in said notches, said lever coming into or out ofenga ement with a movable contact according y as the said lever isdisengaged from or engaged in said notch, an electromotor driving thedisplacing mechanism of the pictures. the circuit of said motorincluding said lever and said movable contact means imposing on theassemblage of said lever and said contact rectilinear reci meetingmovements ap roximately para el to the borders of sai pictures.

In testimony whereof I afiix my signature.
